This list of unsolved deaths includes well-known cases where:

• The cause of death could not be officially determined.
• The person's identity could not be established after they were found dead.
• The cause is known, but the manner of death (homicide, suicide, accident, overdosing) could not be determined.
• Different official investigations have come to different conclusions.
